1 Claim.

The invention relates to new and useful improvements in metalcontainers, and more particularly to a metal container having a slipcover closure therefor.

An object of the invention is to provide a metal container wherein thecover is held on the container through the frictional grip of spacedprojecting portions carried by the flange of the cover and contactingwith the outer wall of the container.

A further object of the invention is to provide a container of the abovetype wherein the cover and the body wall are constructed so as toprovide an extended seal therebetween.

These and other objects of the invention will in part be obvious andwill be hereinafter more fully disclosed.

Referring to the drawing Figure 1 is a view partly in side elevation andpartly in section of a container embodying the improvements;

Fig. 2 is a view partly in plan and partly in section of the same;

Fig. 3 is an enlarged sectional view on the line 3-3 of Fig. 2, whichline is at one side of a gripping projection, and

Fig. 4 is a similar sectional view on the line 4-4 which line passesthrough a gripping projection.

The improved container comprises a body portion which is preferablycylindrical. A bottom end is seamed thereto in the usual manner. Theupper end of the body portion is closed by an outside slip cover whichis held in sealing engagement with said body portion by spaced grippingprojections frictionally contacting with the outer face of said bodyportion. The body wall isrolled or curled inwardly at its upper end toprovide a closed strengthening bead, that is, the edge portion is curleduntil it contacts the body wall. The body wall is beaded outwardly at ashort dis.- tance below the upper edge. rigid non-flexing wall portionat the bottom end of the container. The cover is provided with adepending flange dimensioned so as to slip down over the body portion,and its inner diameter is slightly larger than the outer diameter of thebody portion. Said cover top has an annular bead directly over the bodywall which forms a recess on its inner face dimensioned so as to fit thehead on the body portion and thus form an extended seal. The flange iscurled outwardly and upwardly but not entirely closed so that it willflex. Between this curl and the top the flange is bent outwardly so asto provide a firm hand grip to aid in the removing of the cover.

This provides a very.

(o1. zen-42) This outwardly extending portion is preferably 7 knurled.The flange at its lower edge portion has a series of inwardly extendinggripping projections or lugs. These projections are dimensioned'so as tomake frictional contact with the e 5 body wall. A circle tangential tothe projections before the cover is applied is of less diameter than theouter diameter of the body portion, and when the cover is forced on, theflange will flex inwardly between the projections permitting saidprojections to move outwardly and pass over the body wall. The curve ofthe bead onthe body aids in the deforming of the flange to permit thegripping projections to seat on the body and it is the spring of theflange that holds the projections in firm gripping contact with the bodywall.

Referring to the illustrated embodiment of the invention, the improvedcontainer 5 consists of a body portion 6 to which a bottom end 5a issecured by double seaming. Said body portion is open at its upper end,and said open end of the body is closed by an outside slip cover 8. Thebody wall at its upper end is curled inwardly so as to form a closedhollow bead 'l and at a short distance below, the body wall is providedwith an outwardly curved bead la. These beads strengthen the open end ofthe body portion and form a substantially rigid non-flexing portion. Thecover 8 has an annular bead 9 directly over the body wall which forms arecess on its inner face dimensioned so as to fit the bead on the bodyportion and thus form an extended seal between the cover and thecontainer. The cover also is provided with a depending flange Illdimensioned so as to slip down over the body portion.- The innerdiameter of this flange is slight: 1y larger than the outer diameter ofthe body portion. The flange is curled outwardly and upwardly at thelower edge thereof to form a hollow bead I I which, due to the fact thatit is not entirely closed will allow the flange to flex. Between thisopen bead II and the top of the cover the flange is bent outwardly so asto provide'a firm hand grip to aid in removing the cover. This outwardlyextending portion is preferably knurled as indicated at l2 in thedrawing.

The flange at its lower edge portion has a series of inwardly extendinggripping projections or lugs l3. These projections are dimensioned so asto make contact with the body wall. A circle tangential to theprojections before the cover is applied is of less diameter than theouter diameter of the body portion. When the cover is forced on, theportion M of the flange between the projections will flex inwardly asshown at l5 in Fig. 2 of the drawing, permitting said projections tomove outwardly and pass over the body wall. The curve of the bead on thebody aids in the deforming of the flange to permit the grippingprojections to seat on the body and it is the spring of the flange thatholds the projections in firm gripping contact with the body wall.

Owing to the firm holding grip of the projections and the extended sealbetween the cover and the container bead, a container is produced whichmay be readily opened and closed and when closed it is practicallyairtight. This makes a container that is of especial value for groundcoffee, which is constantly evolving a gas carrying ofi the volatileconstituents giving flavor and aroma to the coffee. With applicantstight cover, this loss of coffee gas is reduced and deteriorationprevented.

It is obvious that minor changes in the detail of construction andarrangement of the parts may be made without departing from the spiritof the invention as set forth in the appended claim. 1

Having thus described the invention, what I claim as new and desire tosecure by Letters Patent, is

A metal container comprising a body portion having an inwardly curledclosed hollow bead at the upper edge thereof, said body wall having anoutwardly projecting bead therein spaced away from the closed bead, saidbody wall between said beads being substantially of uniform diameter, acover for said body portion having an annular recess disposed above saidhollow bead and a flange closely fitting said body wall in the region ofthe closed bead at the upper end thereof, said flange having aprojecting portion substantially at right angles to the body walldisposed opposite the lower portion of the closed bead when a cover isseated on the container body, said cover flange having a portion thereofdepending from the outer edge of said last-named projecting portion,said last-named depending portion being inclined rearwardly toward thebody and knurled, the lower edge portion of said flange being rolledoutwardly to provide a bead and having widely spaced projecting portionsdisposed and dimensioned so as to frictionally grip the outer face ofthe body wall between said beads for holding the cover in sealed contactwith said body portion.
